Novak Djokovic went out in the semifinals at the 2025 Australian Open due to a thigh injury, which forced him to retire after the first set against Alexander Zverev. The former world No.1 received several boos when he left the Rod Laver Arena and gave a thumbs up in a tongue-in-cheek way in response to the crowd who had not liked his retirement.

Novak Djokovic posted a scan of his injured left hamstring on social media Sunday, while taking a shot at fans that booed him for retiring during his semifinal match against Alexander Zverev.
